Hi All,

I am attempting in overriding the behaviour of a an action controller, to be precise, the `TopicsController#latest`, I want to add a custom field to it as part of the response.

And in order to do that I have created a plugin, with:

```plaintext
after_initialize do
  class TopicsController 
    def latest
      render json: MultiJson.dump( "test": "ashdjagds" ); 
    end     
  end
end

```

But it does not work when I make a request, I mean it does not return the {“test”: “ashdjagds” } part,

Any suggestion ?

You should check the class first. We don’t have `latest` method in `TopicsController`. Instead you need to override the [`ListController`](https://github.com/discourse/discourse/blob/18f50ca01abfa5497b3dc423470c3b5e84e48771/app/controllers/list_controller.rb#L58).
